A million Amiibo on May 29 and about a dozen of them were Fire Emblem.
Nintendo is rapidly increasing their internal demand figures of Amiibo after huge recent sales and continued gray market demand.
In an interview with CNET at E3, Reggie Fils-Amie stated "We're at a point where we have to take our volume estimates and double them or triple them based on the levels of demand we're seeing". Reggie also confirmed that a million of the Amiibo announced in April were sold in 30 days in the US, which would cover Smash Brothers wave 4, the silver Mario and the Splatoon series.
Word of an Amiibo reprint leaked out just before E3, which will include restocks of some of the rare Amiibo from the Smash Bros wave.
